Genuine OEM INFINITI G37 Parts — Coupe, Sedan and Convertible 2008–2013

Shop genuine OEM INFINITI G37 parts from INFINITI of Akron for all body styles — two-door coupe, four-door sedan, and two-door convertible — for model years 2008 through 2013. The 3.7L VQ37VHR is one of the most acclaimed naturally aspirated performance engines ever produced, renowned for its high-revving character and long-term reliability. Every G37 part we sell carries the original factory part number and Nissan manufacturer warranty. Nissan continues to supply genuine OEM G37 parts through its active distribution network.

G37 Body Styles — What Interchanges and What Does Not

The G37 was sold in three distinct body styles, each with specific parts that do not interchange despite sharing the same chassis and VQ37VHR engine:

  • G37 Coupe (V36 chassis): Two-door with unique hood, front fenders, doors, rear quarter panels, and shorter roofline. Journey and Sport trim variants with different suspension and brake specifications.
  • G37 Sedan (V36 chassis): Four-door with completely different body panels from the coupe including doors, fenders, quarter panels, and hood. Sport trim uses upgraded suspension and Brembo brakes.
  • G37 Convertible (CV36 chassis): Two-door with retractable hardtop system. Unique rear quarter panels, trunk configuration, top mechanism components, and reinforced chassis structure for open-top rigidity. Many convertible-specific structural components are unique to this body style.

Mechanical components — VQ37VHR engine, front and rear suspension architecture, and braking system layout — are largely consistent across body styles. Sport Package Brembo front brakes are consistent across coupe and sedan Sport variants.

The VQ37VHR — Four Catalytic Converters, High-Rev Maintenance

The VQ37VHR uses a four-converter catalytic system unique to this engine:

  • Bank 1 pre-catalytic converter — Positioned close to the right cylinder bank exhaust manifold for fast light-off.
  • Bank 2 pre-catalytic converter — Positioned close to the left cylinder bank exhaust manifold.
  • Bank 1 main catalytic converter — Downstream larger converter for primary emissions reduction.
  • Bank 2 main catalytic converter — Downstream larger converter, mirror position to bank 1.

All four carry different OEM part numbers. High-mileage G37s frequently need converter replacement because the VQ37VHR's sustained high-rev operation cycles converters through greater thermal stress than lower-revving engines. Always confirm which of the four positions needs replacement before ordering.

Sport Package — Brembo Brakes and Upgraded Suspension

G37 Sport Package models are equipped with Brembo four-piston front calipers and larger diameter rotors with unique OEM part numbers. Installing standard G37 brake pads on Brembo calipers results in improper fitment. Sport models also use front struts and rear shocks with different spring rates and damper valving from base trim — these carry different OEM part numbers and produce noticeably different handling if the wrong specification is installed.

Frequently Asked Questions

Are genuine OEM INFINITI G37 parts still available?

Yes. Nissan continues to supply genuine OEM G37 parts through its active parts distribution network. Common wear items, engine components, suspension parts, and brake components remain in regular stock. Some lower-volume body panels and trim pieces may require 3–7 business days from the distribution center. INFINITI of Akron stocks the most commonly ordered G37 parts and can source the full OEM catalog for any G37 repair project.

What is the most common repair on a high-mileage INFINITI G37?

At higher mileage, catalytic converter replacement is the most common significant G37 repair. The VQ37VHR high-rev operation puts greater thermal stress on converters than lower-revving engines, accelerating substrate degradation. Spark plug replacement, oxygen sensor replacement, suspension component wear, and Brembo brake service on Sport models are also common high-mileage items. All are available as genuine OEM parts from INFINITI of Akron.

Is the INFINITI G37 reliable at high mileage?

The INFINITI G37 is widely regarded as one of the more reliable luxury performance cars of its era. The VQ37VHR engine is known for durability when maintained with OEM-specification parts and regular oil changes. Many G37s are actively driven past 150,000 and 200,000 miles. The enthusiast community around the G37 is large and active, and Nissan continues to support the model with OEM parts — both positive indicators for long-term ownership.
